TAPE-TYPE DISPOSABLE DIAPER

WIPO Patent Application WO/2019/181914

A1

[Problem] To prevent a projection section which expands to the outside in a wave-shaped portion from becoming folded between the surface of a diaper and the skin. [Solution] A lower edge (70, 75) of a wing part (WP) has a wave-shaped portion (80) having a plurality of crest sections that expand outwardly. To a portion of a side flat part (SF) more toward the center in the width direction than the wing part (WP), a side elastic member (64) and a planar gather that is contracted in the front-back direction (LD) by the side elastic member (64) are provided. The side flat part has an overlapping range (77) in which a front-back direction range where the contraction force of the side elastic member (64) acts overlaps with at least a part of a front-back direction range of the wave-shaped portion (80). The maximum extension of the planar gather is 150 to 350%, and a width direction (WD) interval of the side elastic member (64) and the wave-shaped portion (80) in the overlapping range (77) is a maximum of 15 to 50 mm and a minimum of 5 to 20 mm.
